noexcept is missing for begin() end(). That leads to problem that breaks clang.
I manually modify the header file and it works.

It looks like this cleanup patch has some issues. Probably need a new test file
for clang.

There are no tests using clang.

Fixed now, thanks for the report.
I do have local tests that I run with Clang, but they're not automated and not
part of the upstream testsuite, so I didn't notice this bug. My local clang
tests do pass again now.
